No specimens have been seen capturing prey, but the stomach of preserved specimens contained small crustaceans, mostly copepods. The bell shape of the web, along with mucus produced by glands around the mouth, maybe be used to capture zooplankton. The bioluminescence of the suckers is also thought to be used to attract prey, but this has not yet been confirmed.

Animal Foods: aquatic crustaceans; zooplankton

Primary Diet: carnivore (Eats non-insect arthropods); planktivore
